Measuring the changing cost of cybercrime
Ross Anderson,Chris Barton,Rainer Bölme,Richard Clayton,Carlos Gañán,Tom Grasso,Michael Levi,Tyler Moore,Marie Vasek +8 more
TL;DR: It would be economically rational to spend less in anticipation of cybercrime (on antivirus, rewalls, etc.) and more on response, and to be particularly bad at prosecuting criminals who operate infrastructure that other wrongdoers exploit.

Plug and Prey? Measuring the Commoditization of Cybercrime via Online Anonymous Markets
Rolf van Wegberg,Samaneh Tajalizadehkhoob,Kyle Soska,Ugur Akyazi,Carlos Gañán,Bram Klievink,Nicolas Christin,Michel van Eeten +7 more
TL;DR: A conceptual model of the value chain components for dominant criminal business models is developed and the market supply for these components over time is identified, finding evidence of commoditization in most components, but the outsourcing options are highly restricted and transaction volume is often modest.
Understanding the Role of Sender Reputation in Abuse Reporting and Cleanup.
TL;DR: In this article, the authors present the first randomized controlled experiment into sender reputation and find that detailed abuse reports significantly increase cleanup rates and that the evasiveness of the attacker in hiding compromise can substantially hamper cleanup efforts.
Proceedings ArticleDOI
Cleaning Up the Internet of Evil Things: Real-World Evidence on ISP and Consumer Efforts to Remove Mirai
Orcun Cetin,Carlos Gañán,Lisette Altena,Takahiro Kasama,Daisuke Inoue,Kazuki Tamiya,Ying Tie,Katsunari Yoshioka,Michel van Eeten +8 more
TL;DR: It is found that quarantining and notifying infected customers via a walled garden, a best practice from ISP botnet mitigation for conventional malware, remediates 92% of the infections within 14 days, compared to lab tests, which observed reinfection of real IoT devices within minutes.
Journal ArticleDOI
EPA: An efficient and privacy-aware revocation mechanism for vehicular ad hoc networks
TL;DR: This paper proposes an Efficient and Privacy-Aware revocation Mechanism (EPA) based on the use of Merkle Hash Trees (MHT) and a Crowds-based anonymous protocol, which replaces the time-consuming certificate revocation lists checking process.
